COFFEE ROASTER.

SZ ECIFECATION forming part of Letters Patent No. 309,147, dated December 9. 1884.

Be it known that 1, JOHN JUs'r, a citizen of the United States, and a resident of Sank City, in the county of Sank and State of Visconsin, have invented certain new and useful Improvements in Coffee-Roasters; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a perspective view of my improved coffee-roaster with a portion of the bowl and easing broken away. Fig. 2 is a vertical section of the same. Fig. 3 is a bottom view of the cover, and Fig. 4 is a perspective view of the stirrer.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to coffee-masters; and it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the bowl or pot, which is preferably a so-called Scotch bowl or a metallic pot nearly hemispherical; and B indicates the cover, which has a downwardly-projecting flange, G, which fits into the top of the bowl, and is provided with a handle, D, for the purpose of removing it. The top of the cover has a circular aperture, E, which is covered with a small flanged lid or cover, F, having an alarm-whistle, Gr, consisting of two eoneavo convex plates having registering perforations, of a construction similar to the toy whistles placed between the teeth and the lips. A plate, H, is secured downwardly projecting and diagonally upon the under side of the top of the cover, and has two inclined flanges, II, bent at right angles to the plate and inclined from the edges of the cover to the central horizontal flange, J, of the plate, which is likewise bent at right angles to the plate, and has a central perforation, K, registering with a perforation, L, in the top of the cover, through which perforations the stirrer-stem passes, and

a radial brace, M, passes from the outer edge of the central flange to the edge of the top of (No model.)

the cover. The stirrer-stem N is provided with a crank, O, at its upper end, by which it may be turned, the stem turning in the perforations in the top of the cover and in the central flange of the diametrical brace-plate, and is provided at its lower end with stirringwings consisting of astrip of metal, 1?, secured at its middle to the lower end of the stem, projecting toward the sides of the pot, in which it rotates, and slightly twisted, with thelower edges of the radiating portions Q projecting in the direction of the rotation, the said portions thus being slightly inclined, whereupon the ends of these inclined radiating portions are curved upward, with their edges in the circle of rotation, as shown at Q, and bent inward, and secured to the stem a distance above the lower end, the said inwardly-bent portions B being twisted'in a plane parallel with the plane of thelowerportions. In. this manner it will be seen that the lower twisted radiating portions of the stirrer will scrape the concave bottom of the bowl'and raise the coffee-beans over their inclined sides, while the curved ends will scrape the beans from the sides, thus preventing them from sticking to the bottom or sides of the bowl, and stirring and turning them effectually. It will be seen that the coffee emitting a quantity of steam the whistle will be blown when sufficient steam is developed, which will, by necessary adjustment of the whistle, take place when the coffee is nearly roasted, giving warning that it is time for removing the bowl.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States 1. The stirrer consisting of the stem and of of a strip of metal secured to the stem at its middle, to the lower end of the same, and at its ends to the stem above the end, having the lower radiating portions inclined in the direction of the rotation, having the upwardlycurved portions twisted in the circle of rota tion, and having the upper inwardly-bent portions parallel with the lower portions, as and for the purpose shown and set forth.

2. In a coffee-roaster, the combination of the bowl, the cover having the downwardlyprojecting flange, the aperture in its top, the

central hearing or perforation, and the diaas described, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affiixed my signature to in presence of two witnesses.

JOHN J UST.
